Elite road racers demand the best - Dura-Ace components are precision engineered for ultimate performance and durability
Improved Freehub body design for quick pawl engagement (125% faster than previous Dura-Ace) for instant power transfer
Oversized axle has increased rigidity torsionally and laterally removing axle flex when under compression from the quick release, thus improving rotational smoothness and durability
Labyrinth double contact sealing - low-friction seals effectively shut out water, mud and dirt without affecting rotational smoothness
Borozon treated bearing races - super mirror finish bearing races reduce friction providing silky smooth and precise bearing rotation
Cold forged and machined aluminium hub shell and oversized 7075 alloy axle combined with a titanium freewheel body all keep the wheel weight to a minimum
Quick and easy bearing assembly and maintenance via a simple to use digital click adjuster removing the need for cone spanners
8, 9 and 10-speed compatible titanium Freehub body
